'lhisinventionrelates to slide carriers and i has for its object to provide a device otthis characteradapted to properly position slide before a light projecting machine.

. It is the primary object of the invention to provide a carrier. of this character capable of holding atplurality of illustrating slides and wherein the slides may be quickly brought .into 1 carrier; i It is another object of the invention to provide a carrier of this character capable of being applied. to conventional types of and wherein position bymerely rotating the supporting shaft of the; carrier for locking the carrier when the slides thereof are propin any number of slides may be used, the

erly positioned beforeithe lightprojecting lensot the machine; e. v

It is sti'll a further. object 01": theinvention to provide a carrier of this character where slides being changed after thecarrier has made one complete revolution,w1thout re= quiring the carrier to be; disengaged from the machine or interfering with the slide that is inuse.

With these and ot-herobjects in view the invention consists 1n the lmproved construetion and arrangement ofparts tobe herein5 after more particularly described, fully claimed andillustrated in theaccompanying drawings in which q Figure lis a plan view of a slide carrler constructed in accordance with an embodiment of the invention, i

Figure 2 is an end elevation, Figure 3 is a sectionalyview taken on the line 33 of Figure 1, and i Figured is a detailed View of the holding spring. i y i Referring to the drawings 5 designates a body member or plate preferably circular in form and having a head 6 provided at its outer edge to reinforce the plate. A plurality of openings 7 are provided in the plate, said I openings being I preferably rec- 1921. Serial no. lGSJASO.

tangular and are so positioned that they substantially radiateiirom the center of the ,late so that when one of the openings is )rought before the lens of the light projecting machine the side of the opening will be p parallel to the vertical.

. Eachof the openings 7 isprovided with guide members 8, all of said guide members being disposed on the same side of the body member. The guide members extend down both sides ofythe openings and across the end of the openings adjacent the center of the body member. The ends of the openlugs adjacent the periphery of the plate are unobstructed to provide an entranceto the guide members.

In order to prevent accidental disengage.

ment of the slides from the openings, an

opening 9 is provided in the body member between the periphery of the body member I and the adjacent end of the opening. A retaining spring lOis secured atone end to i one side face of the body member. passed over the periphery ofthe body. member and through the opening '9. The ,end of the spring is extended at right angles to prevent accidental disengagement of the end of the spring from the opening, By this means spring may be compressed to permit the insertion of the slide and when released re turns to its former position and engages the The central portion of the body member 5 is provided with an opening 11. in which a sleeve 12 is mounted. said sleevebeing secured to the body member, a portion thereof projecting on both sides of the body mem her. This sleeve is intended to receive a supporting shaft A which is carriedby the light projecting machine (not shown). Secured to and projecting from one side face of the body member 5 is a collar 13, said collar being disposed. in spaced relation to the sleeve 12 and being formed with many sides. each side being disposed substantially parallel to the end of the adjacent opening.

A plurality of recesses 14 are provided in the outer edge of the collar, said recesses be ing disposed substantially at the intermediate portions of each of the sides of the collar.

In order to maintain the opening in the proper position before the rays of the light projecting machine there is provided a novel holding means consisting ota holding finger 15 constructed from a single length of resilient' material. The end 16 oi the finger is formed into an eye adapted to receive the end of the shaft A. The intermediate portion of the finger is substantially erimped or bent to increase the resiliency thereof, the end 17 of the finger projecting over and. beyond the edge of the collar 13. In the application of the finger the end of the shaft A is proi ided with a nut 18 and the eye or end16 of the finger is engaged with the shaft. A second nut-19 isthre aded on the shaft sopas to firmly clamp'the end 16 of theflfinger to the shaft and between the nuts: 18 and 19. 'lt' will be noted that the crimped portion of the finger is disposed at all times inwardly of the collar that there is no danger of objects coming in contact with the crimped portion and thereby interfering; with the holdingi power of the finger.

In use, after the slides are applied to the carrier, the stem is rotated on the shaft A. so as to bring thedesired slide into position. The slide is maintained in the proper position bycontact of the finger 15 with the'wall of the adjacent recess 1 It is of course on vious that the resiliency of the finger 15 does not interfere with the carrier being;

rotated when it is desired to change the slide as the end 17 of the finger projects beyond the collar, and may be i asped by the operator so as to disengage the finger from the collar and permit the carrier or body member to be rotated without causing thesame to be locked when the recesses pass the finger From the foregoing; it will. be readily seen. that this invention prorides a novel. term. of slide carrier simple in construction and one that ma r be readilv i) )liGCl to anv lie'ht y .1 Ll

projecting; machine. Another important feature of this carrier 1s that it is not nee-- essary to reverse the slide when applying the same to the carrier, as the slide may be inserted in the guides in an upright position at the top of? the carrier so that when the carrier is rotated the slide will be reversed or turned when the portion of the carrier holding the slide reaches the light projecting): lens.

What is claimed is 1. A. slide carrier of tle character described embodying a supporting shaft. :1 body member mounted on the shaft, a collar carried by the body member and surrounding); the shaft in spaced relation thereto, said collar havinga plurality of recesses. and a resilient holdingmember secured to the shaft and 'i'rictionally engaging the collar, said holding member being" arranged to alternately enter the recesses upon movement of the body member on the shaft to prevent movement of the body member in either direction.

2. A slide carrier of the character described embodying a supporting shaft. :1 body member rotatably mounted on the shaft, said body member having a. plurality of substantially radiating slide openings, a collar secured to one side face of the body member. the outer surface of said collar being disposed substantially parallel to the end of the adjacent opening, a resilient holding" finger secured to the shaft. said holding finger extending inwardly of and over the C(lfIQ oi? the collar and arranged to :lirictionally engage the edge to position said openings centrally of the linger and lock the body member to the shall.

in testimony whereof I hereunto allix my signature.
